ELECTRICAL SPECIFICATIONS FOR PIC16F54/57
Absolute Maximum Ratings()
Ambient Temperature under bias ......................................................................................................... -40°C to +125°C
Storage Temperature ........................................................................................................................... -65°C to +150°C
Voltage on VDD with respect to VSS ............................................................................................................ 0V to +6.5V
Voltage on MCLR with respect to VSS(1) ................................................................................................... 0V to +13.5V
Voltage on all other pins with respect to VSS ............................................................................... -0.6V to (VDD + 0.6V)
Total power dissipation(2) .................................................................................................................................. 800 mW
Max. current out of VSS pin ................................................................................................................................ 150 mA
Max. current into VDD pin ................................................................................................................................... 100 mA
Max. current into an input pin (T0CKI only)....................................................................................................... ±500
μA
Input clamp current, IIK (VI < 0 or VI > VDD) ....................................................................................................... ±20 mA
Output clamp current, IOK (VO < 0 or VO > VDD) ................................................................................................ ±20 mA
Max. output current sunk by any I/O pin .............................................................................................................. 25 mA
Max. output current sourced by any I/O pin ......................................................................................................... 25 mA
Max. output current sourced by a single I/O port (PORTA, B or C) ..................................................................... 50 mA
Max. output current sunk by a single I/O port (PORTA, B or C)........................................................................... 50 mA
Note 1: Voltage spikes below VSS at the MCLR pin, inducing currents greater than 80 mA, may cause latch-up.
Thus, a series resistor of 50 to 100
Ω should be used when applying a “l(fā)ow” level to the MCLR pin rather
than pulling this pin directly to VSS.
2: Power Dissipation is calculated as follows: Pdis = VDD x {IDD –
∑ IOH} + ∑ {(VDD – VOH) x IOH} + ∑(VOL x IOL)
NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
